**Inheritance:**
java.lang.Object
```
public final class CalculationPrecisionStrategy
```

Enumerates strategies for handling calculation precision. Because of the precision issue of IEEE 754 Floating-Point Arithmetic, some "seemingly simple" formulas may not be calculated as the expected result. Such as formula "=-0.45+0.43+0.02", when calculating operands by '+' operator directly, the result is not zero. For such kind of precision issue, some special strategies may give the expected result.
## Fields

| Field | Description |
| --- | --- |
| [DECIMAL](#DECIMAL) | Uses decimal as operands when possible. |
| [NONE](#NONE) | No strategy applied on calculation. |
| [ROUND](#ROUND) | Rounds the calculation result according with significant digits. |
## Methods

| Method | Description |
| --- | --- |
| [equals(Object arg0)](#equals-java.lang.Object-) |  |
| [getClass()](#getClass--) |  |
| [hashCode()](#hashCode--) |  |
| [notify()](#notify--) |  |
| [notifyAll()](#notifyAll--) |  |
| [toString()](#toString--) |  |
| [wait()](#wait--) |  |
| [wait(long arg0)](#wait-long-) |  |
| [wait(long arg0, int arg1)](#wait-long-int-) |  |
### DECIMAL {#DECIMAL}
```
public static final int DECIMAL
```


Uses decimal as operands when possible. Most inefficient for performance.

### NONE {#NONE}
```
public static final int NONE
```


No strategy applied on calculation. When calculating just use the original double value as operand and return the result directly. Most efficient for performance and applicable for most cases.

### ROUND {#ROUND}
```
public static final int ROUND
```


Rounds the calculation result according with significant digits.

### equals(Object arg0) {#equals-java.lang.Object-}
```
public boolean equals(Object arg0)
```

```




**Returns:**
java.lang.String
### wait() {#wait--}
```
